I don't know if Telesoft was planning on big DoD money, but they were strenously encouraged for *years* by a certain oil company to come up with a decent Cray Ada compiler. The same oil company then found out that the folks who superoptimized the Cray Fortran compiler didn't work at Cray any longer, and Cray themself conceeded they "basically couldn't explain how it worked" at that point in time (this was several+ years ago). So much for technology sharing... It was rather a large disappointment, but I'm not sure I would call it a token effort either. -- Richard G.
